Description

Technical Field

[0001] This utility model relates to the field of floor lamp technology, and in particular to a floor lamp structure. Background Technology

[0002] As a common lighting fixture that combines illumination and decoration, adjustable lamp head angle is an important design requirement for floor lamps. Existing floor lamps typically use a rotating joint to allow the lamp head to tilt or rotate horizontally to adapt to different lighting scenarios. However, the circuit connections of these products generally rely on flexible cables (such as rubber-insulated wires), which need to extend from the lamp base through the rotating joint to the lamp head to power the light source (such as LED modules or bulbs).

[0003] When the lamp head rotates continuously in one direction, the cable will accumulate tangles as it rotates, causing internal wires to twist, insulation to wear down, and even short circuits or open circuits. For example, some floor lamps allow the lamp head to swing within a range of ±90°, but beyond this range, the cable will twist excessively and become deformed, potentially leading to wire breakage with prolonged use.

[0004] To avoid cable damage, existing products typically use mechanical limiting devices (such as protruding buckles or limiting baffles) to restrict the rotation angle of the lamp head, allowing it to be adjusted only within a small range (such as oscillating back and forth within 180°), and thus unable to achieve 360° unlimited rotation. Utility Model Content

[0005] The purpose of this utility model is to provide a floor lamp structure that addresses the defects and shortcomings of the existing technology.

[0008] The connector assembly includes a first connector and a second connector rotatably connected to the first connector; a DC power plug is fixed on the first connector; and a DC power socket for use with the DC power plug is fixed on the second connector.

[0009] Furthermore, the first connector is provided with an internal threaded hole; the outer wall of the DC power socket is provided with an external thread that matches the internal threaded hole; the external thread is threadedly connected to the internal threaded hole.

[0011] Furthermore, the lamp head can be any one of the following shapes: ring shape, circle shape, elliptical shape, elliptical ring shape, and strip shape.

[0012] Furthermore, the lamp head is a ring-shaped lamp head; a fixing rod is fixed on the inner side wall of the ring-shaped lamp head; the connector assembly is connected between the fixing rod and the connecting rod; the connector assembly is located at an off-center position of the ring-shaped lamp head.

[0013] Furthermore, the column is a hollow tube; a connecting plate is fixed on the base; the upper and lower surfaces of the base are respectively provided with an upper countersunk hole and a lower countersunk hole; the connecting plate is embedded in the upper countersunk hole; a bottom limiting piece is provided in the lower countersunk hole; the bottom limiting piece and the connecting plate are connected and fixed by bolts; the connecting plate is provided with an insert post that matches the inner hole of the column; a side threaded hole is provided on the side wall of the insert post; a side through hole is provided on the outer side wall of the column; the insert post is inserted into the inner cavity of the column; and the insert post and the column are fixed together by bolts passing through the side through hole and threaded onto the side threaded hole.

[0014] Furthermore, the bottom of the base is evenly distributed with multiple anti-slip pads.

[0033] The connector assembly 3 includes a first connector 301 and a second connector 305 rotatably connected to the first connector 301; a DC power plug 303 is fixed on the first connector 301; and a DC power socket 302 for use with the DC power plug 303 is fixed on the second connector 305.

[0034] The DC power plug 303 and DC power socket 302 are not fundamentally different from the prior art, so they will not be described in detail. One electrode of the DC power plug 303 is a cylindrical needle structure, and the other electrode of the DC power plug 303 is a cylindrical shell that is sleeved on the outside of the cylindrical needle.

[0035] The two electrode plates of the DC power plug 303 are coaxially arranged with a cylindrical structure; the cylindrical pin structure electrode plate on the DC power plug 303 is inserted into the inner cylinder of the DC power plug 303 to form a rotating connection and electrical connection; while the cylindrical shell electrode on the DC power plug 303 is fitted onto the outer ring of the DC power socket 302 and electrically connected.

[0036] The first connector assembly 3 has its first connector 301 and DC power socket 302 fixed to the column 2 and the connecting rod 4, respectively; the second connector assembly 3 has its first connector 301 and DC power socket 302 fixed to the connecting rod 4 and the lamp holder 7, respectively.

[0037] One end of the wire on the column 2 is connected to the DC power socket 302 inside the first connector assembly 3; one end of the wire inside the connecting rod 4 is connected to the DC power plug 303 inside the first connector assembly 3; the other end of the wire inside the connecting rod 4 is connected to the DC power socket 302 inside the second connector assembly 3; the lamp holder 7 is connected to the DC power plug 303 of the second connector assembly 3; thus, the wire on the column 2 and the lamp holder 7 are electrically connected, and the connector assembly 3 acts as a pivot, allowing the connecting rod 4 to rotate on the column 2; the lamp holder 7 can rotate on the connecting rod 4; the rotatable electrical connection achieved through the DC power plug 303 and the DC power socket 302 allows the lamp holder 7 and the connecting rod 4 to rotate to any angle without damaging the cable, making it more convenient to use.

[0038] In a preferred embodiment of this utility model, the first connecting seat 301 is provided with an internal threaded hole 30101; the outer wall of the DC power socket 302 is provided with an external thread 30201 that matches the internal threaded hole 30101; the external thread 30201 is threadedly connected to the internal threaded hole 30101.

[0039] The DC power socket 302 and the first connector 301 are connected and fixed by a threaded connection, which facilitates the disassembly and replacement of the DC power socket 302.

[0041] Both the rotating sleeve 304 and the DC power socket 302 have metal housings. The weight of the second connecting seat 305 and the connecting rod 4 or lamp holder 7 connected to the second connecting seat 305 prevents the rotating sleeve 304 from coming loose from the DC power socket 302. The rotating sleeve 304 is coated with lubricating oil, which enables the rotational connection between the DC power socket 302 and the DC power plug 303, and the rotational connection between the first connecting seat 301 and the second connecting seat 305. When the lamp holder 7 needs to be removed from the connecting rod 4 or the connecting rod 4 needs to be removed from the column 2, it can be directly pulled out along the axial direction of the DC power socket 302 to separate the first connecting seat 301 and the second connecting seat 305. In this structure, the first connecting seat 301 and the second connecting seat 305 are easy to assemble and disassemble, which facilitates the assembly of the lamp.

[0042] In a preferred embodiment of this utility model, the lamp head 7 is any one of the following shapes: ring shape, circle shape, elliptical shape, elliptical ring shape, and strip shape.

After passing through the countersunk hole, the connecting plate 8 and the bottom limiting piece 9 are connected and fixed together by threaded connection to the threaded hole; the connecting plate 8 is provided with a pin 801 that matches the inner hole of the column 2; the side wall of the pin 801 is provided with a side threaded hole 80101; the outer side wall of the column 2 is provided with a side through hole 201; the pin 801 is inserted into the inner cavity of the column 2; after passing through the side through hole 201, the pin 801 and the column 2 are fixed together by threaded connection to the side threaded hole 80101 by bolt;
